Rainfall last year vs. rainfall yesterday

72 hr ending rainfall: July 25th, 2010
July 26th, 2011 to July 28th, 2011













Do these two images look sort of similar?  The top left is the 72 hour rainfall totals from last year when major flooding occurred over northeast Iowa and northern Illinois.  The second one is the doppler estimated rainfall totals from late Tuesday night through 9am Thursday morning.  The areas that were hardest hit last year during the July 22nd through July 25th rain event were, for the most part, hit hard with this last storm.  The heavy rain last year did extend a little further east into the Rockford area.  This year the heaviest rain was more confined to northwest Illinois.
